- Solar power expansion has surpassed expectations since the turn of the century, becoming a major global energy source.
- Global solar capacity skyrocketed from 228 GW in 2015 to an estimated 2,919 GW in 2025, supplying about 10% of world energy, surpassing nuclear.
- China leads in solar capacity, installing 315 GW in 2025 for a total of 1,300 GW, with over 80% of panels produced there.
- The EU ranks second with 406 GW capacity, covering roughly 13% of its electricity demand, with countries like Greece and Spain exceeding 20% solar share.
- The US, despite policy challenges, ranks third with 267 GW supplying 8% of electricity, while coal power dropped significantly from 2015 to 2025.
- Solar energy is significantly cheaper, with costs down by 90%, making it the cheapest electricity in many regions, as low as 1 cent per kWh in sunny areas.
- Solar power is transforming transport and heating, enabling cost savings in electric vehicles and heat pumps, especially when paired with rooftop solar panels.
- Solar is projected to become the world's most important energy source, with models suggesting it could supply 76% of global energy in a cost-effective system.
- Challenges include expanding grids and storage for nighttime use, with digitalization needed for optimal coordination of consumption and generation.
